摘　　要：从煤柱的载荷和强度展开研究,基于小煤柱载荷计算公式以及冯国瑞教授推导的上部煤层开采支撑压力向下传递公式,给出了煤柱受上部采场最大集中应力影响的载荷表达式,并以西山煤电白家庄矿为工程背景对多重采动下煤柱的稳定性进行了分析。Load and strength from pillar study, based on a formula passed down small coal pillar load calculation formula and the upper coal seam pressure support professor FENG Guo-rui derivation is given first pillar of the upper part of the largest concentrations of stope stress load expression and then combined with the actual situation Xishan coal mine Baijiazhuang multiple stability study under pillar mining.

关 键 词：残采 双重采动 煤柱稳定性
